If you have lived in Plano for any length of time, you know the sting of a red imported fire ant. You also probably know the thin line of tiny ants that appears across the kitchen counter every spring. North Texas supports a long list of ant species, and the right fix depends on identifying the one you have.
Ant species that matter around Plano
- Red imported fire ants build dome-shaped mounds in open lawns, along sidewalks and around sprinkler heads. Disturb one and hundreds of aggressive workers boil out.
- Odorous house ants are small, dark and smell like rotten coconut when crushed. They enter kitchens for sweets and often nest in wall voids.
- Pavement ants nest under slabs and driveway cracks and push up sand piles at the edges.
- Carpenter ants excavate damp or damaged wood, a risk around old fence posts, leaky roof valleys and mature oaks.
- Argentine ants appear in some Texas neighborhoods, moving in large trails and making huge, multi-queen colonies.
Why North Texas weather matters
Wet springs soften the clay soil, and ants rebuild quickly after storms. Fire ant colonies will relocate to higher ground when flooding rains hit, sometimes moving into yards and even electrical boxes. In summer drought, ants look for moisture indoors, and the cool damp spots near water heaters and bathrooms become appealing. In neighborhoods near Plano's creeks and parks, tree canopy encourages carpenter ants as well.
What professional treatment looks like
For fire ants, providers frequently use a two-step method: broadcast bait over the whole yard so workers carry it back to queens, followed by individual mound treatment where children or pets play. Indoor trailing ants are tackled with baits, barrier products around the foundation and targeted treatments of entry points. Carpenter ants require locating the parent colony, which may be inside a wall, so inspection of moisture-damaged wood is central.
Technicians also recommend what the household can change. A leaking hose bib or a mulch bed piled against brick veneer may be the reason ants keep coming.
Timing also plays a part. Fire ant bait works best when workers are actively foraging, which usually means mild, dry weather with soil temperatures that are warm but not scorching. Providers in Plano often schedule broadcast treatments in spring and again in early fall, and they will skip the hottest part of the day. Ask your provider about timing so you know when to keep kids and pets off the lawn.
Prevention steps
- Rake mulch back from the foundation and avoid piling it high.
- Repair leaks and reduce sprinkler overspray near the house.
- Wipe sticky spills and rinse recycling before binning it.
- Store pet food in sealed bins and do not leave bowls out overnight.
- Check fence posts, deck boards and trees for soft or rotting wood.

Plano ant FAQ
How dangerous is a fire ant sting?
Stings are painful and can cause pustules. People with allergies can have severe reactions and should seek medical care.
Why do I see ants even though I keep the kitchen clean?
Ants can follow moisture or nest inside walls; a clean counter may not stop scouts looking for water.
Does rain wash fire ants away?
Rarely. They float together and relocate, then rebuild nearby.
Are carpenter ants a sign of structural damage?
They suggest moisture-damaged wood somewhere, and damage can develop over time, so inspect and fix the source.
